Curtain crane bracket



Aug. 13, 1940. w. LEMLE 'CURTAIN CRANE BRACKET Filed Feb. 18, 1939 Patented Aug. 13, 1940 UNITED STATES PATENT yOFFICE 5 Claims.

The invention relates generally to supports. More particularly the invention relates to that type of support which serves to sustain in a horizontal position a crane for a curtain.

One object of the invention is to provide a support of this type which is adjustable to bringthe crane into ltruly horizontal position, which is simple in construction, and can be easily applied to a wall or frame.

Another object of the invention is to provide a curtain-crane support which comprises a bracket-section with a socket for the pivotshank of the crane and a hole for an attaching screw, a separate section with a hole for a screw for attaching it to a wall or frame, and screwmeans between the two sections for adjusting the section with the socket to retain the crane truly horizontal. y

Other objects of the invention will be apparent from a consideration of the following detailed description.

The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at ,the conclusion hereof.

In the drawing: Fig. 1 is a front elevation vof a crane support embodying the invention. Fig. 2 is an enlarged section on the line 2-2 of Fig. 1. Fig. 3 is a section onV the line 3 3 of Fig. 2. Fig. 4 is a perspective of the bracket-section. Fig. 5 is a perspective of the socket section which is carried by the bracket-section and is adjustable relatively to said bracket-section .so that the crane may be positioned at different distances from the wall or frame.

The invention is exemplified in connection with a crane a on which a curtain b is suspended in any manner, as well understood in the art. The crane is provided with a vertical pivot-stud or shank a1 so that it may be swung into position parallel with the wall or at right angles thereto. The improved support which constitutes the invention comprises a bracket-section c and section d. These two sections are separate from each other and are each separately attachable to the wall or frame. Bracket-section c comprises an upstanding or vertical lug c1 which fits against the frame or wall e and is provided with a hole c2 for an attaching screw e1; a vertically extending side c3, which extends substantially at right angles from the face of the wall or frame and outwardly therefrom; a horizontal top flange c4 on side c3; a lower horizontal ange c5 on side c3; and a downwardly extending lug c6 with a screw-threaded hole c".

(Cl. 248-265) :jaja

Lug c1, side c3, flanges c4; c5 and downwardly extending lug c'i are integrally formed and are preferably stamped from sheet metal.

In addition to the sections c and d the support comprises a socket-section f. This section 5- consists of a cylindrical member f1 for the pivotstud ai of the crane a, and a flat member Jl? which ts vertically between the flanges c4, c5 and against side cl. Member f2 is provided with an elongated slot f3 for a screw f4 whereby the l0 socket-member may be adjustably secured in bracket 'c to position the socket f1 different distances from the wall or frame e. Section f may be 'formed of plate or sheet metal bent to form cylinder member f1 and folded upon itself to 15v form flat member f2. The pivot-stud a1 of the crane is provided with a shoulder a2 which rests on the top member f1, and with 'a depending stop a3 which extends into a cut-away portion f5 at the top of said member and co-acts there- 2o with to limit the horizontal pivotal movement of .the crane. l

Section d comprises a member or lug which fits against the wall or frame e and is provided with a hole dl for a screw e for attaching the 25 section d to lthe frame or wall. Section d also comprises an integral lug d3 which projects outwardly from the wall and is providedwith a hole d4 extending therethrough.

A screw y is threaded to hole c" in lug c6 and 30 is provided with an unthreaded cylindrical portion g1 which lextends through hole d4 and is provided with shoulders g2. 'Ihe latter engage the front and back faces of lug d3 and serve to hold the screw against longitudinal movement 35 relatively to section d while at the same time permitting the screw to rotate relatively to the lug.

In mounting the support on a wall or frame, sections c and d are positioned so that holes c2 and d1 are vertically aligned. Thereafter screw e1 is driven into the wall or frame to secure the section b thereon and screw e2 is driven into the frame or wall to secure section d thereon. After both sections have been thus secured, screw y is adjusted to swing section c pivotally on screw e1 to position cylinder member f1 so that the crane a will be truly horizontal. Rotation of screw g by reason of its threaded engagement with depending lug cs of section c, moves said 50 lug c6 to or from lug d3 on section d and causes section c to swing laterally. This adjustment may be utilized during the mounting of the crane on the frame or wall and also to compensate for y any sagging of then crane. The cylindrical por- 55 tion g1 of screw g fits loosely in the hole through which it passes in lug d3 of section d to permit a slight pivotal movement of the screw With section c during adjustment of the latter. Lug c6 is provided with a lip o9 which extends under lug d3 of section d to hold said section against excessive rotation of screw g before the support is mounted on the wall or frame a.

The invention exemplies a curtain-crane support which is simple in construction, and provides for adjustment of the socket for the pivot-stud of the crane between two bracket-sections which are separately secured to the wall or frame. The support is simple in construction and can be fabricated from sheet or plate metal. The socket-member is slidably adjustable in the bracket for positioning the socket for the pivotstud of the crane diierent distances from the frame or wall. I

The invention is not to be understood as restricted to the detailsset forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

'Having thus described the invention, what I claim as new and desire to secure by Letters Patent is:

l. A curtain-crane support comprising the combination of a pair of separate bracket-sections each provided with a lug adapted to fit against and having a hole for means for pivotally attaching one section to a wall or frame, a socket-member for the pivot-stud of the crane on one bracket-section, and a screw between the bracket-sections for pivotally adjusting one section on the wall or frame and relatively to the other section for positioning the socket to retain the crane truly horizontal;

2. A curtain-crane support comprising the combination of a pairof separate bracket-sections each provided with a lug adapted to fit against and having a hole for means for pivotally attaching one section to a wall or frame, a socket-member for the pivot-stud of the crane on one bracket-section, and a screw rotatable and held against axial movement in one section and screw-threaded to the other section for pivotally adjusting one section on the wall and relatively to the other section for positioning the socket to retain the crane truly horizontal.
